Update Shared printers on the client
In order to properly update the shared printers on the client, first update the Print2Email on the host computer.
Once the host is updated, remove/uninstall the shared printer from the client based on the Remove/Uninstall Shared printers from Client computers section.
Once removed, configure and share the printers on the host computer based on the Printer Sharing section, and add the shared printer on the client.
In case the Print2Email is locked, please reboot the computer or restart the spooler service by opening a command line (cmd.exe) as Administrator, and type the following commands and then try to add the shared printer to the client again:
net stop spooler
net start spooler
